Description

This discrete MOSFET brushless motor controller is based on Allegro’s A89301 BLDC driver and enables sensorless control of one brushless DC motor. It supports a wide 5.5 V to 48 V operating voltage range and can continuously deliver up to 11 A motor current without a heat sink or forced air. The A89301 supports four control interfaces: analog voltage, PWM duty cycle, pulse frequency, and I²C. The I²C interface also allows configuration of various settings on the A89301, and we provide a configuration utility for Windows that simplifies setup with one of our USB-to-I²C adapters. This version ships with soldered header pins and terminal blocks.
